Hi
Has any of you W210 E55 owners ever changed the relay for secondary air pump? I cannot find it. In the K40 box there is one black relay, is it that one?
Thank you
EDIT: Following info is somewhat incorrect. Please see my next post.
Schematic for the facelift version shows the Battery Protection Relay (BPR) co-located with the secondary air injection pump relay in the passenger side fuse/relay box. My pre-facelift version (January 1999 build date) only has one relay in that area and I assume it is the BPR relay. STAR Finder might assist; I'll see about making time to fire up the computer and take a look at that and the schematics.
